Professor Ankermann

A Siedentopf, who had established a cattle ranch on the crater bottom, and his assistant Rothe discovered mounds near their homestead in 1912 and soon recognised them as burial cairns. They were later examined by Drs Reck (in 1913) and Arning (in 1915), who found in one of them the skeletons of a man, a woman and, lying between them, of a child.

.... Professor Ankermann - in an appendix to Reck's paper - states that the Ngorongoro tombs show several similarities with. but also contrasts to, those of Engaruka, but that both types prove Hamitic origin. He is unable to decide their age but doubts whether they should be ascribed to a Neolithic culture, as Reck does.
